CONDENSER FOR C SPEcIFICATIoN forming 'part of Letters Annina-MACHINES.

Patent No. 357,478, dated February 8, 1887.

Application filed April 24, 1886. Serial No, 200,046. (No model.)

To all whom it may concern:

Be it known that I, WEBsTERGILL, a citizen of the United States,residing at Camden, in the county of vCamden and State of New Jersey,have invented certain new and useful Improvements in Condensers forGarding-Machines; and I dohereby declare the following to be a full,clear, and exact description of the invention, reference being had tothe accompanying drawingswhich form part of this specification, inwhich- Fgure 1 is a plan view of a condenser with Fig. 2 is a sideelevation of the same.

My invention has for its object to provide means whereby the sliver, asit comes from the doffer of a carding-machine, may be twisted and drawnbefore it reaches the-condenser aprons,for the purpose of reducing andrendering it more compact before being acted upon by the rubbing-aprons.

Carders have generally recognized the difficulty of drawing wool withthe devices now in use, which consist of a train of rolls of increasingspeed, owing to the fact that the sliver, if not twisted, will not bearmuch draft without breaking, and have also appreciated the fact that itwould be desirable to give the sliver considerable draft, in order tobring it into better condition for spinning on the mule. It is a factthat if a sliverof wool be subjected to` much draft it will break orpart, and that if it be twisted while being drawn the twist will go tothe weakest part of the sliver and 'strengthen the same,any breakingthat may occur thereafter `taking place in the untwisted portion. Wherea partial separation of sliver takes place it results in unevenness inthe yarn when spun'.

I have discovered that by the means I provide a twist may be imparted tothe sliver between the doffer of the carding-machine and therubbing-aprons ofthe condenser, whereby such sliver may be drawn, thetwisting enabling the draft to be effected without destroying theuniformity of the slubbing, and the draft rendering such slubbing morecompact and in better form to be acted upon by the rubbing-aprons thanlit would otherwise be.

My invention consists, essentially, in the provision of two cross beltsor aprons between the doffer-roll of the cardng-machine and thecondenser rubbing-aprons, and arranged obliquely or diagonally to theshafts of both the dot'f'er-roll and the rubbing-aprons, being solocated that they receive the sliver from the carding-machine anddeliver it to the rubbingf aprons, imparting a twist to such sliver andproducing a draft upon the latter in its passage.

Referring to the accompanyingdrawings, A represents a frame, which maybe the frame of the condenser, on which are supported rubbing-aprons BB, mounted on rolls C C, whose axes or spindles e e have alongitudinalreciprocation imparted to them, while they rotate densers by meansofeccentrics E E,or by other equivalent mechanism.

F represents the dofier-roll, and F 'an additional roll, which twocombined constitute tening end of the carding-machine or upon the` frameA.

G and H represent two aprons, of the same material and construction asare usually employed for the rubbing-aprons of condensers forcarding-machines, and which are mounted upon rolls g g and h h, thelatter having bear- A. These aprons and their rolls are located betweenthe rubbing-aprons B B and the tension-rolls F F', and said aprons G andH are arranged obliquely or diagonally with reference-to the axes orspindl'esof the rubbingapron rolls and doffer or tension rolls.

, Any suitable form of gearing or belting may be employed to communicatemotion to the aprons G and H, which I designate as twistaprons.7 theirroller-shafts as having pulleys I and K, which receive belts Yz' and k,passing over pulleys Z Z on a cross-shaft, L, having bearings in theframe A. These belts revolve in the direction of the arrows m i, and inoperation run at such speed that they will produce draft on the sliverdelivered to them by the tensionrolls F F', or from the doffer of thecardingmachine.

The various belts and pulleys shown in the drawings (which are not ofthe essence of my invention) are designated as follows: A belt, f,running on pulley Z2 on shaft L, and on a in the usual manner ofrubbing-aprons of con-V sion-rollers, and which may be on thedischargings in uprights or standards g h on the frame In the drawings Ihave illustrated pulley, j, on shaft of roller F, communicates motion tosaid roller. A belt, m, running from large pulley M on shaft L around apulley, P, on the shaft ofthe eccentries E E, communicates rotary motionto said shaft, and a crossed belt, N, running over a pulley, l,

on shaft L, thence around a pulley, a, on one of the shafts of the upperrubbing-apron B, thence around an idler-pulley (not shown in lodrawings) to a pulley, a', on one of the shafts of the lower apron B,communicates rotary motion to therolls C C, and causes said aprons totravel.

The sliver, as it comes from the cardingmachine, passes between therollers F F', and thence between the belt G and belt H, said beltsimparting a twist to and imposing draft upon such sliver, so that thelatter is both twisted and drawn as it comes from the 2o doifer beforedelivery to the rubbing-aprons B B. The twist given to the sliver is apeculiar one in this, that it is made as said sliver enters to thetwist-aprons and beeois undone as it passes therefrom.- i's to permitdraft tobe imposed on the sliver without injurious results, and theeffect of the draft is to make the sliver more compact, so that it isdelivered to the condensing rollers or aprons in the form of a roll orslubbing al- 3o ready partially condensed, the twist-aprons not onlytwisting the sliver, but also drawing it, as said aprons move fasterthan the tensionrolls F F.

I have illustrated the condenser as having aprons on the upper and lowerrolls; but, as the rubbing-aprons are not my invent-ion, one apronacting` against rolls may be used; or, if desirable, the rubbing-apronsmay be dispeused with and the rubbing be effected by 4o means of upperand lower rolls.

, 1f desired, the twist-aprons may be supported upon a separate framefrom frame A, .and the tension-rollers, which are illustrated in thedrawings as being upon said frame A,

may be supported upon the 'frame of the card- Tne effect of riiaust"ing-machine, said tension-rollers consisting of the usual dofi'er-rollcrand an additional roller, forming a pair of rollers whose surfaces areso close as to cause them to bind upon the sliver in its passing throughthem.

What I claim as my invention is 1. rlhe combination, with rubbing apronsor rollsfor a cardingmachine, of twist-aprons G and H, which cross eachother and are arranged diagonally with respect to the axes or spindlesof the rubbing rolls or aprons, substantially as shown and described.

2. The combination, with the doienroll of a cardingmachine and rubbingaprons or rolls therefor, of twist-aprons located between thedoffer-roll and the rubbing aprons or rolls, said twistaprons crossingeach other, and being arranged diagonally with respect to the axes ofthe doier-roll and rubbing-rolls, substantially as shown and described.

3. The combination, with rubbing aprons or rolls and the doff'er andtension rolls of a carding-machine,of two aprons mounted on rollers andprovided with mechanism whereby said aprons are caused to run fasterthan the doffer and tension rolls, said aprons crossing each other, andbeing arranged diagonally with reference to the dot'fer-roll andrubbing-apron axes or spindles, whereby the sliver in its passage fromthe dofl'er-roll to the rubbingaprons is twisted and drawn,substantially as shown and described.

4. The combination, with tension-rollers F F and rubbing aprons orrolls, of intermediate twist-aprons crossing each other and diagonallyarranged, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this19th day oi' April, 1886. A
